The multi-stage filtration system utilizes the entire canister volume for radically increased water flow efficiency.

The multi-stage filtration system utilizes the entire canister volume for radically increased water flow efficiency. Its mechanical stage features vertical twin foam pre-filters to increase flow and reduce maintenance. The chemical and biological stages are housed in independent modules. This means you can change filter media independently and ensure a constant level of all-important nitrifying bacteria.

The multiple modules allow a vast array of filter media options for maximum versatility. Use the basic filtration media included or customize filtration by combining up to three unique media in the configuration that's just right for your system. This unparalleled level of flexibility allows you to perfect your own aquatic environment. Ideal for professional aquarist and the serious hobbyist, alike.

Comes ready to use with the following Fluval media: foam pads, carbon, and BioMax

Leaking issues
I would highly recommend searching the internet and reading all the complaints about Fluval. This product worked fine until I had to open it and now I cannot get the canister to stop leaking. Bought a new O ring and replaced the clamps. No not buy.

About the filter
This filter is wonderful!! It's a little more expensive than the filters you see in the store (which I have always used), but it is soooo much better. I have never seen the water so clear as it is now. My friends have been using one for a while, and tell me that it actually needs cleaning much less than what it recommends. I love this filter, the water is sparkling!

Good Product, wish I had gone to the next size up.
The filter was easy to set up once I read through the instructions. I bought the filter for a 46 gallon tank. I wish I had gone up to the next size. I was afraid the 304 was going to be too powerful. I wish it had been clear that it is possible to adjust the output somewhat.
